# Carousel, Slider and Thumbnail Push
{% hint style="danger" %}
**Warning:**
You should build your application with **Xcode 8 or higher** to use iOS10 media push on your application.
{% endhint %}
## Step 1: Create New Target
1. **Ensure** Xcode 8 or higher is installed.
2. **In Xcode**: Navigate to **File > New > Target**.
3. Select **Notification Content Extension**.
4. A new class named **NotificationViewController** will be created. **Extend** it from `NetmeraNotificationContentExtension`.
{% hint style="info" %}
**Switching Back to Debugging**
If you accidentally "Activate", you can return to debugging your app using Xcode, which is located alongside the play button.
{% endhint %}
## Step 2: Add your Project to Pod File
1. **Remove** the Objective-C Bridging Header file.
2. Add `NetmeraNotificationContentExtension` in the NotificationContent.swift file.
3. In your **Podfile**, add:
```ruby
target 'your_content_extension_target_name' do
pod "Netmera/NotificationContentExtension"
end
```
4. **Run `pod update`** to apply the changes.
{% hint style="danger" %}
**Warning**: Run `pod update` after editing the Podfile.
{% endhint %}
## Step 3: Add Code to Notification Content Extension Class
1. The new **NotificationViewController** class should extend `NetmeraNotificationContentExtension`
{% tabs %}
{% tab title="Swift" %}
```
class NotificationViewController: NetmeraNotificationContentExtension {
override func viewDidLoad() {
super.viewDidLoad()
// Do any required interface initialization here.
}
}
```
{% endtab %}
{% tab title="Objective-C" %}
```java
#import
#import
@interface NotificationViewController : NetmeraNotificationContentExtension
@end
```
```
#import "NotificationViewController.h"
#import
#import
@interface NotificationViewController ()
@end
@implementation NotificationViewController
- (void)viewDidLoad {
[super viewDidLoad];
// If you want to change the background color, uncomment the next line
// self.view.backgroundColor = [UIColor whiteColor];
}
@end
```
{% endtab %}
{% endtabs %}
## Step 4: Info.plist Configuration
1. Make sure the **info.plist** file under the content extension looks like this.
```xml
AppGroupNameyour group nameNSAppTransportSecurityNSAllowsArbitraryLoadsNSExtensionNSExtensionAttributesUNNotificationExtensionCategoryNetmeraGeneralNetmeraCarouselUNNotificationExtensionInitialContentSizeRatio1NSExtensionMainStoryboardMainInterfaceNSExtensionPointIdentifiercom.apple.usernotifications.content-extension
```
2. Delete **Label** in `MainInterface`
3. If you want to add slide action to Carousel property, `UserInteractionEnabled` must be set **`YES`**.
4. Enable App Groups for both your application and the NotificationContent extension in the Capabilities settings of your project. Then add "**group.com.yourcompany.carousel**" to your app groups.
5. Specify the app group name in the app delegate method where you set the **`Netmera.start()`** method. Use the following codes as examples:
{% tabs %}
{% tab title="Swift" %}
```swift
Netmera.setAppGroupName = "group.com.yourcompany.carousel"
```
{% endtab %}
{% tab title="Objective-C" %}
```objectivec
[Netmera setAppGroupName:@"group.com.yourcompany.carousel"];
```
{% endtab %}
{% endtabs %}
